Three phase step-down transformers receive electricity from a power line and reduce the voltage, delivering the appropriate, lower voltage to the equipment or facility. These transformers are used in power distribution applications, heavy equipment like elevators, industrial automation, and large-scale manufacturing industries like mining and petrochemical processing.

Three phase step-up transformers receive electricity from a power line and increase the voltage, delivering the appropriate, higher voltage to the equipment or facility. These transformers are used in power generation applications, industrial automation, and large-scale manufacturing industries like mining and petrochemical processing.

Harsh-environment three phase transformers protect the equipment inside from harsh outdoor conditions like rain, ice, and snow. They carry electricity between three phase setups.

Harmonic mitigating three phase transformers reduce voltage distortion and power loss to distribution systems. These transformers are used in setups with equipment like personal computers, copiers, and adjustable speed drives, which introduce harmful harmonic currents into a system.
